Title: Magnetic preloading of bearings in rotating machines
Inventor: HANS FREDRIK KJELLNES
IPC: F16C32/06
Filed: 2016-10-31
Abstract: In a rotating machine 240 having a vertically oriented rotating shaft 110 a static magnetic force provided by magnets 330, 350 is used to simulate rotor weight and create the desired bearing preload in hydrodynamic journal bearings 122, 126 & 340. By installing a magnet 330, 350 the gravity based preload on the shaft journal bearings 122, 126, 340 of a horizontal machine can be simulated for a vertical shaft 110. This can increase rotor stability, reduce the machines vulnerability to hydraulically induced imbalance forces and give a more smooth transition through various shaft speeds.

Abstract: A spinning reel with a bail reversing mechanism including an engagement member 60 for engaging the bail arm and a switching member 64, where at least part of the switching member 64 is accommodated in a recess 12g of the reel body 12. When a rotor rotates in a line-winding direction, the attitude of a bail arm is switched from a line-releasing attitude to a line-winding attitude, as the engagement member engages the bail arm. The switching member 64 may have a first end portion, a second end portion where at least a part is thicker than the first end portion, and an intermediate portion, between the first and second end portions, configured to come into contact with and guide the engagement member along an axis of rotation with the rotor. The distal end of the first end portion may be accommodated in the accommodation recess. The switching member may have an attachment portion [64d, figure 8a] to engage a recess in a flange on the reel body housing. Conventional switching members have a tapered shape. Accommodating the part with the smallest thickness in the recess prevents it deforming when affected by environmental (e.g. temperature) changes.

Title: Method and apparatus for encoding and decoding a video stream with subpictures
Inventor: NAËL OUEDRAOGO
IPC: H04N19/96
Filed: 2019-09-27
Abstract: Video coding where pictures are divided into subpictures and are coded into a bitstream. For at least one subpicture, information indicating a location of a splitting inference boundary is coded; and a Coding Tree Block (CTB) containing the at least one subpicture is coded into the bitstream. The size of an image in a video bitstream may not correspond to a multiple of the size of CTBs, which means that the right or bottom boundary of an image may cross the rightmost or bottommost CTB. Typically, coding blocks falling outside the image are not encoded, but the present invention overcomes this problem by splitting the picture into subpictures and enabling an inferred split of the CTBs. If the height or width of a subpicture is not a multiple of the size of the CTB, a flag may be encoded to indicate that a splitting inference process is required. The location information may include the number of horizontal and vertical boundaries as well as the location of boundary. The present invention may be used in Versatile Video Coding VVC.
